The title says it all. I have had this issue for some time now and would like to get it addressed one of these days now considering we're starting to expect good weather and that gives me the time. Should i start at the EBTCM? or shall i start with a speed sensor? any suggestions are helpful. I do know that usually the ABS light and all these warnings for suspension would only come on as soon as my wheels start rolling, but now it seems its starting to come up as soon as its started and running from time to time. I also know that my ABS has been disabled because of this (brakes dont click on slippery roads). Once i have this last issue fixed, then i have resolved all issues other than the slight oil leak.

Pull and post any DTC's and their definitions. Anything else is pure speculation.

P053 (history) = Distributor Signal Interrupt
P061 = Cruise // Vent Solenoid problem (this is current but not worried about cruise)
P109 (history) = Keep Alive Memory (KAM) Reset/PCM has lost primary battery power (just recently been doing work with battery/alternator)

T061 = Motor Pump Circuit Fault (T codes are related to ABS system and traction control/suspension so this may be it!)

S011 = Left Front Damper Solenoid Valve Short to Ground/Open
S016 = Right Front Damper Solenoid Valve Short to Ground/Open
S060 = Left Front Position Sensor Fault
(i really wouldnt worry about the S codes, i have aftermarket suspension in front)

You live in road salt "liberal" Chicago I would look at cables & connections in the wheel wells & grounds opens or corrosion.

I would check volts at fuses with a VOM for battery current a test light won't tell you volts.

The S codes are giving you the service suspension message, the T061 code is giving you the ABS lamp, the motor is either stalled or open circuited. A good place to start is the ground lead that comes off the ABS module and attaches to the subframe just outboard of the ABs module. If that wire is broken or the ground connection is rusty that will cause issues with the ABS pump motor.

What is the status of your T061 code? I get the same thing intermittently. Sometimes doesn't happen for a long time.
